How does speed affect rearward amplification?
- A.Speed cancels amplification
- B.Amplification only occurs below 25 mph
- C.Speed affects only the tractor
- D.Higher speed makes the whip effect stronger and leaves less time to correct a swing
Correct answer
D. Higher speed makes the whip effect stronger and leaves less time to correct a swing
Why
The same steering input at higher speed produces larger lateral forces all along the combination. Slowing down is therefore both prevention and cure for sway.
